Revision of Pocadius Erichson (Coleoptera: Nitidulidae)
A revision of Pocadius Erichson (Coleoptera: Nitidulidae) was completed. A total of 46 species were (re)described, including 25 new species, a key to species constructed, and phylogenetic analysis performed. Taxonomic changes, including nomenclatural emendations, reinstatement of species, and …

Chemical Ecology of Clytini (Coleoptera: Cerambycidae)
In chapter six, I characterize the contact sex pheromone of N. a. acuminatus. Males recognize female conspecifics only after contacting them with their antennae. I characterize the behavior and demonstrate that three methylalkanes present in the wax layer of females are sufficient to elicit a …

Recognition in burying beetles (Nicrophorus spp., Silphidae, Coleoptera)
Burying beetles (Nicrophorus spp.) meet potential partners on carcasses. The aim of this study was to determine how males and females are able to determine potential partners from individuals of different species. The cuticular hydrocarbons of various species of European and Canadian burying …

Prey-mediated effects of imidacloprid on Laricobius nigrinus (Coleoptera: Derodontidae) and Sasajiscymnus tsugae (Coleoptera: Coccinellidae), two predators of hemlock woolly adelgid
Prey-mediated effects of imidacloprid were evaluated for Laricobius nigrinus Fender and Sasajiscymnus tsugae Sasaji and McClure after feeding on hemlock woolly adelgid (HWA), Adelges tsugae Annand (Hemiptera: Adelgidae). Two methods were evaluated for detecting imidacloprid in hemlock tissues: a …

Biology and host finding of predaceous hister beetles (Coleoptera: Histeridae) associated with Ips spp. (Coleoptera: Scolytidae) in loblolly pine (Pinus taeda L.)
The most common predaceous Histeridae (Coleoptera) found associated with Ips engraver beetles (Coleoptera: Scolytidae) in Louisiana were Platysoma attenuata LeConte, Pla. cylindrica (Paykull), Pla. parallelum (Say), and Plegaderus transversus (Say). Seasonal abundance of histerids in flight traps …

Wood trait preferences of Neotropical xylophagous beetles (Coleoptera: Cerambycidae)
<p>Tree life history strategies are correlated with functional plant traits, such as wood density (WD), moisture content (MC), bark thickness (BT), and nitrogen content (N); these traits affect the nutrients available to xylophagous insects. Cerambycid beetles feed on substrates that vary in these …
